Activate the integrated PLC
0 = Off: the PLC is not active, the frequency inverter is actuated in accordance with parameters
(P509) and (P510).
1 = To: the PLC is active, frequency inverter is actuated via the PLC, depending on (P351).
The definition of the main setpoints must be carried out accordingly in parameter (P553).
Auxiliary setpoints (P510[-02]) can still be defined via (P546).

Selection of the source for the control word (STW) and the main setpoint (HSW) with active PLC
functionality (P350 = 1). With the settings "0" and "1", the main setpoints are defined via (P553),
but the definition of the auxiliary setpoints remains unchanged via (P546). This parameter is only
taken over if the frequency inverter is in "Ready to start" status.
0 = STW & HSW = PLC: The PLC supplies the control word (STW) and the main setpoint
(HSW), and parameters (P509) and (P510[-01]) have no effect.
1 = STW = P509: The PLC supplies the main setpoint (HSW), the control word (STW)
corresponds to the setting in parameter (P509)
2 = HSW = P510[1]: The PLC supplies the control word (STW), the source for the main
setpoint (HSW) corresponds to the setting in parameter (P510[-01])
3 = STW & HSW = P509/510: The source for the control word (STW) and the main setpoint
(HSW) corresponds to the setting in parameter (P509)/(P510[-01])

Bus status via PLC

0 ... 3
{ 0 }
This parameter can be used to determine how the control word (STW) for the master function and
the status word (ZSW) of the frequency inverter undergo further processing by the PLC.
0 = Off: The control word (STW) of the master function (P503≠0) and the status word (ZSW)
undergo further processing by the PLC without change.
1 = STW for broadcast: The control word (STW) for the master value function (P503≠0) is set
by the PLC. In order to do this, the control word must be redefined in the PLC using
process value "34_PLC_Busmaster_Control_word".
2 = ZSW for bus: The status word (ZSW) of the frequency inverter is set by the PLC. In order
to do this, the status word must be redefined in the PLC using process value
"28_PLC_status_word".
3 = STW Broadcast&ZSWBus: See setting 1 and 2
